The Chao and Fagbenle’s modification of Merk series has been employed for the analysis of forced convection laminar thermal boundary layer transfer for non-isothermal surfaces. In addition to the Prandtl number (Pr) and the pressure gradient (∧), a third parameter (temperature parameter, γ ) was introduced in the analysis. Solutions of the resulting universal functions for the thermal boundary layer have been obtained for Pr of 0.70, 1.0 and 10.0 and for a range of ∧ . The results obtained for the similarity equations agreed with published results within very close limits for all the ∧’s investigated.

Abstract:
Large areas of the indigenous tropical forests in the southwestern part of Nigeria are being converted into agricultural lands and this has been reported to have serious implications for biodiversity and the environment. Cocoa based agroforestry is one of the common agricultural practices in this region and comparative information on the carbon storage capacity of the cocoa agroforests is generally lacking. In this study the above-ground carbon storage and partitioning in a protected primary forest were evaluated and compared with those of the two categories of cocoa agroforests (sparse and dense) identified in the area. Above-ground biomass accumulation and carbon stock varied significantly with land use type, with the primary rainforest having the highest values and sparse cocoa agroforests having the lowest. A reduction in above-ground carbon stock of 89.82% and 71.20% was observed 10 years after conversion of tropical rainforest to sparse and dense cocoa agroforests respectively.

Abstract:
The study of investigated the influence of class and age of secondary school students on inclination to crime. The descriptive research design of the survey type was used for the study. The population for the study are all 219 public secondary school in Ekiti. The questionnaire titled Iinclination To Crime (ITC) among secondary school student was administered on the junior and senior secondary school students. The validity of the instrument was ensured using face and content validity. The test retest reliability of the instrument was ensured by administering 30 copies of the instrument on subject that are not part of the sample on 2 acetous of 2 weeks interoal. A reliability of 0.86 was obtained and found significant at 0.05 level of significance using person product moment correlation analysis. Copies of the final instrument with personally administered by the researcher. The data collected were analyzed using inferential statistics of t-test. The result of the analysis showed that there are significant differences in the tendencies to commit crime by the junior students on senior students and there are marked differences in the ages the students are inclined to crime. Based on the teachers and counselor should consider the level of aberrant students and their ages while counseling them.

Abstract:
In CDMA communication systems, all the subscribers share the common channel. The limitation factor on the system’s capacity is not the bandwidth, but multiuser interference and the near far problem. This paper models CDMA system from the perspective of mobile radio channels corrupted by additive white noise generated by multipath and multiple access interferences. The system’s receiver is assisted using different combining diversity techniques. Performance analysis of the system with these detection techniques is presented. The paper demonstrates that combining diversity techniques in the system’s receivers markedly improve the performance of CDMA systems.

Abstract:
In wireless Code Division Multiple Access (CDMA) system, the use of power control is indispensable to combat near-far and fading problems. Signals transmitted over a multipath propagation channel which exhibits inter-path interference and fading. The receiver has to employ measures to mitigate these effects or it will incur severe performance degradation. A classic approach in CDMA communications is the rake receiver. In this paper, the downlink performance is estimated for a CDMA mobile system at the vertex of multiple adjacent cells. At the base station the received signal is coherently dispread and demodulated using a rake receiver. The effects of power control, error correction and rake receiver were also investigated on the assumption that the received signals undergo Rayleigh fading, lognormal shadowing, and frequency selective fading. The evaluation of performance measures of base to mobile link (downlink) of a multiple-cell CDMA mobile system is presented. This study demonstrates that significant performance improvements are achievable with combined use of power control, rake receiver and error correction scheme.

A 5-year mean seasonal analysis of mean
storm height data and histogramsfrom the Tropical Rainfall Measuring Mission
(TRMM) Precipitation Radar (PR) have been used to study the storm structure of
the major climatic regions in Africa and over the adjacent Atlantic ocean. The
analysis was carried out in two ways. First, the mean storm height and histogram
were analyzed for the entire continent bounded by 40?N to 40?S and 20?W to 60?E. Secondly, the analysis was carried out
on sub-regional basis, on which Africa was structured into ten regions: Desert (North), Semi-desert
(north), Deciduous forest (North), Brush Grass Savanna (North), Tropical
Rainforest, Deciduous forest (South), Brush Grass-Savanna (South), Temperate
Grassland/Montane Forest, Steppe (East) and Atlantic Ocean. As observed over
Africa, and some parts of the Atlantic Ocean and the Indian
Ocean, the storm height over the land is higher than that over the sea because
ground surfaces tend to be heated more and convections are more easily
developed over the land than over the Ocean. There are high storm counts over
the land at 250mb whereas the storm
counts are high over the Ocean at 700mb. Over the regions, the vertical structure of the histograms reveals a
distinct bi-modal distribution in the northern hemisphere and the southern
hemisphere, but a unimodal
distribution

Abstract:
In this work, three models are used to analyze the electric load capacity of a fast growing urban city and to estimate its future consumption. Ikorodu, the case-study location is a highly populated city whose energy demand is continuously increasing. The ultimate focus of this study is to establish a basis for the comparison of different electric load consumption for the existing populace and to provide estimates for the future planning of the city. In this work, three different models have been used to present more accurate load predictions and to enhance proper comparison of results. Among numerous mathematical and scientific models that are applicable to this kind of task, the compound-growth method, the linear model approach and the cubic model have been chosen to enhance diversity in load analysis. The futuristic scheme to be harnessed will fall within the ranges of values obtained from the three different models used in forecasting. This paper concludes with issues pertaining to economics of load utilization as it affects substantive planning.

Abstract:
Reincarnation is the belief that after someone dies; his immortal soul separates from the body and lives again in another physical body. The traditional Yorùbá culture holds the belief in reincarnation (atunwaye). Atunwaye is believed to be possible in three different forms which are: ipadawaye (ancestor’s rebirth), akudaaya (die and reappear) and abiku (born to die). Yorùbá people of Akure also hold on to the traditional belief in atunwaye. The article used the philosophical tools of analysis and evaluation to examine reincarnation beliefs among the Yorùbá people in general and Akure people in particular. Oral interviews were also conducted among indigenes of Akure, to understand their beliefs on reincarnation. Findings show that Yorùbá people of Akure also hold on to traditional belief in reincarnation (atunwaye) in its various forms. The research concludes that reincarnation is an established belief among the Yorùbá people in general and the Akure people in particular. It is also noted that this belief has survived despite the influence of Christianity and Islam on the culture of Akure people.

Abstract:
Obstructive sleep apnea syndrome is a common disorder with significant health consequences and is on the rise in consonance with the obesity pandemic. In view of the association between sleep-disordered breathing and pulmonary hypertension as depicted by multiple studies, current clinical practice guidelines categorize obstructive sleep apnea as a risk factor for pulmonary hypertension and recommend an assessment for sleep disordered breathing in evaluating patients with pulmonary hypertension. The dysregulatory mechanisms associated with hypoxemic episodes observed in sleep related breathing disorders contribute to the onset of pulmonary hypertension and identification of these potentially treatable factors might help in the reduction of overall cardiovascular mortality. 1. Introduction In consonance with the obesity pandemic, there is an increasing awareness of sleep-related breathing disorders (SRBDs) as a potentially treatable factor in reducing overall cardiovascular mortality. The spectrum of SRBD ranges from habitual snoring to obstructive sleep apnea (OSA) and increasing evidence shows that improved cardiovascular function may be obtained by early recognition and treatment of these disorders [1]. Over the past three decades, the pathophysiology of sleep-related breathing disorders (SRBDs) has been better understood and though the exact contributory pathways are still not clearly defined several studies allude to multi-factorial mechanisms being involved in the development of pulmonary hypertension in relation to SRBD [1]. Sleep apnea occurs in about 12 million US adults in their 4th to 6th decades of life and about a quarter of all those are over the age of 65？yrs. Nearly half of all nursing home residents have sleep apnea and 38,000 deaths annually are directly attributed to SRBD. With the prevalence of SRBD currently exceeding that of asthma in adults, the cardiovascular consequences of its associated comorbidities especially pulmonary hypertension (PH) have been of significant interest in recent years [1]. The most recent classification system of pulmonary hypertension was published in the 2009 European Society of Cardiology Guidelines where the definition of PH was based on an increased mean pulmonary arterial pressure >？25？mmHg at rest. This broadly encompasses all clinical subgroups of PH as outlined by the 4th World Symposium on Pulmonary Hypertension in Dana Point, California, in 2008. This update classifies Group 1 as pulmonary arterial hypertension (PAH) due to idiopathic, heritable, or drug- and toxin-induced causes; it also includes
